CS-15560 : Improve HVM logging of hosts
When a host is not considered for deployment because it has disabled HVM, then call that out
in the logs for debugging.

This addresses bug CS-15560.


  server/src/com/cloud/agent/manager/allocator/impl/ 0f163cc 



1) Deployed a Simulator Environment with two Simulator hosts
2) marked a host as non-HVM and template as HVM enabled
         * update host set capabilities=NULL where id=1;
         * update vm_template set hvm=1 where id=10;
3) restart MS for the VOs to refresh
4) deploy VM using the template
5) Verified the non-HVM hosts are called out in the logs

Logs shown as below:
2012-07-13 12:07:58,904 DEBUG [allocator.impl.FirstFitAllocator] (Job-Executor-9:job-30 FirstFitRoutingAllocator)
Not considering hosts: [Host[-1-Routing]]  to deploy template: Tmpl[10-VHD-simulator-Centos
as they are not HVM enabled
